Description

Technical Field

[0001] The utility model relates to the technical field of textiles, in particular to a multi-station sock turning machine with automatic thread end trimming. Background Art

[0002] During the production process of socks, it is usually necessary to sew the ends of the socks. After sewing, the excess thread needs to be trimmed, and then the socks need to be turned over before the next process can be carried out. The socks that have just been cut are usually inside out, and they need to be turned over before being sold.

[0003] During the production process of existing socks, thread ends often remain inside the socks, and there are even more thread ends inside jacquard socks. The length of the thread ends generated by jacquard is different from that of the thread ends remaining during sock production. Traditional machines cut the thread ends of socks short, but if all of them are cut off, the thread ends generated by jacquard are likely to fall off, greatly reducing the life of the socks.

[0021] The present invention will be further described below with reference to the accompanying drawings.

[0022] like Figures 1 to 4 As shown in the figure, a multi-station sock turning machine with automatic thread trimming includes a workbench 1, which is installed on the top of a frame 2. No less than three support tubes 3 are arranged through and at intervals on the workbench 1. The lower ends of the support tubes 3 are connected to the top of a box 4, and the box 4 is connected to the lower surface of the workbench 1. A sock pulling mechanism 6 and a trimming mechanism 7 are arranged on the rear side of the support tube 3. The sock pulling mechanism 6 and the trimming mechanism 7 are installed on a slider 8 through a cylinder seat 11. The slider 8 is matched and connected to a track 9. The track 9 is vertically connected to the rear side of the frame 2. A negative pressure tube 5 is arranged on the rear side of the box 4, and a collecting tank 10 is arranged in the frame 2.

[0023] As a further improvement to the above scheme, the sock-rolling mechanism 6 includes a cylinder 62, which is installed at the lower part of the cylinder base 11. The end of the telescopic rod of the cylinder 62 is connected to the clamping arm 63. The arc-shaped opening of the clamping arm 63 is placed on the rear side of the support tube 3. A rubber half-ring 61 is provided on the clamping arm 63. The inner arc surface of the rubber half-ring 61 can completely fit the outer surface of the support tube 6. The cylinder 62 drives the clamping arm 63 to move, and the rubber half-ring 61 on the clamping arm 63 is used to press the tube mouth of the sock to move upward, so that the sock is separated from the support tube 3.

[0024] As a further improvement to the above scheme, the trimming mechanism 7 includes a second cylinder 75, which is installed on the upper part of the cylinder seat 11. The telescopic rod end of the second cylinder 75 is connected to the seat body 74, and the trimming head 73 is connected to the seat body 74. A suction pipe 76 is provided on one side of the trimming head 73. The suction pipe 76 is connected to the seat body 74 through a buckle. The suction pipe 76 is supplied with negative pressure through an air source. After the trimming head 73 is fed by the second cylinder 75, the trimming head 73 trims the thread ends of the socks. The cut thread ends enter the suction pipe 76 under the action of the negative pressure in the suction pipe 76, so as to collect thread ends, wool yarn, etc.

[0025] As a further improvement to the above solution, the inner arc radius of the rubber half ring 61 is smaller than the inner arc radius of the clamping arm 63, so as to prevent the inner arc surface of the metal clamping arm 63 from directly contacting the socks and damaging the socks by contacting the support tube 3. In addition, the inner corners of the end of the rubber half ring 61 are chamfered to prevent the end corners of the rubber half ring 61 from scratching the socks through excessive rounding.

[0026] As a further improvement to the above scheme, a box plate 41 is rotatably set at the lower end of the box 4, and the telescopic rod end of the cylinder three 42 is hinged on the end side of the lower surface of the box plate 41. The cylinder three 42 is rotatably installed on the cylinder plate 43. The cylinder plate 43 is symmetrically connected to the lower side of the end plate of the box 4. The box plate 41 is supported by the cylinder and the box 4 is sealed to ensure the airtightness inside the box 4 and the negative pressure inside the box 4, so that the upper end of the support tube 3 has a sufficient negative pressure value to ensure that the socks enter the box 4 from the support tube 3.

[0027] As a further improvement to the above solution, the peripheral side portions of the frame 2 are connected to side plates 12 for shifting the frame 2 .

[0028] As a further improvement to the above scheme, the trimming head 73 is connected to the pressure cylinder 71 through a pressure-resistant pipe. The pressure cylinder 71 is installed on the seat plate 72. The seat plate 72 is installed on the rear side of the frame 2. The gas or liquid in the pressure cylinder 71 provides air pressure and / or hydraulic pressure for the trimming head 73. The air pressure and / or hydraulic pressure in the pressure cylinder 71 is supplied to the trimming head 73 through the pressure-resistant pipe, and the thread ends at the ends of the socks on the support tube 3 are trimmed by the trimming head 73.

[0029] The working principle of a multi-station hosiery turning machine with automatic thread trimming is as follows: preparation work, first, the box plate 41 is sealed with the box 4 by the cylinder 3 42; then the collecting tank 10 is placed just below the box 4 in the frame 2;

[0030] Then manually put the socks completely on the support tube 3. At this time, the back of the socks is outside. The slider 8 moves on the track 9, so that the trimming head 73 is aligned with the sock end at the upper end of the support tube 3. After the trimming head 73 is fed by the cylinder 2 75, the trimming head 73 trims the thread ends of the sock end. The cut thread ends enter the suction tube 76 under the action of the negative pressure in the suction tube 76, so as to collect thread ends, wool yarn, etc. The telescopic rod of the cylinder 2 75 retracts, so that the trimming head 73 and the suction tube 76 retreat away from the sock end. At this time, the cylinder 1 62 drives the clamping arm 63 to move, and the rubber half ring 61 on the clamping arm 63 presses the tube mouth of the sock. The slider 8 moves upward on the track 9, and the rubber half ring 61 is used to separate the sock from the support tube 3. The end of the sock is first sucked into the support tube 3, and then gradually reaches the end of the sock, thereby achieving the purpose of turning the sock. At this time, the negative pressure at the end of the support tube 3 sucks the sock into the box 4, and then the box plate 41 is opened by the cylinder 3 42, and the sock falls into the collection tank 10.

[0031] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
